Scheda di rete Digitus 4 porte 2,5 Gigabit Ethernet PCI Express chipset Realtek

The Digitus DN-10136 PCIe Quad-Port 2.5G network adapter integrates a four-speed IEEE 802.3–compatible Media Access Controller with four 10/100/1000/2.5GBASE-T transceivers. With a PCI Express x4 interface (2-lane PCIe bus up to 10 Gbps) and support for 2.5G and 1G Lite modes, the card provides wired connectivity for desktops, workstations, servers, communication platforms and embedded systems and supports high-speed transmission over CAT5e UTP (and CAT3 UTP for 10 Mbps).

Advantages

The network card supports IEEE 802.3u, IEEE 802.3ab and IEEE 802.3bz standards and includes features such as pair swap/polarity/skew correction and crossover detection with auto-correction. Its Realtek-based design and PCIe x4 interface deliver reliable multi-port 2.5 Gigabit performance while remaining compatible with existing Ethernet cabling and common networking equipment.

Suitable for

• Desktop PCs requiring multiple wired network ports
• Workstations and servers needing aggregated or separate 2.5G links
• Communication platforms and network appliances
• Embedded systems and industrial PCs with PCI Express slots

How to use

Install the card into an available PCIe x4 (or x8/x16) slot on a powered-off computer and secure it to the chassis. Connect each LAN port to the network using appropriate CAT5e or better UTP cabling for 2.5G operation. After powering on the system, install the operating system drivers provided by the vendor or use the compatible Realtek drivers. Configure IP settings, link aggregation, VLANs or QoS as needed in the host OS or management software.

Recommendations

For reliable 2.5G performance use CAT5e or higher-quality cables and ensure the motherboard BIOS/OS supports PCIe devices; update drivers to the latest Realtek release. For legacy 10 Mbps connections, CAT3 UTP can be used but is not recommended for higher speeds.
